Case Report Of Cryoneurolysis For The Treatment Of Refractory Intercostobrachial Neuralgia With Postherpetic Neuralgia.

Postherpetic neuralgia is a common and potentially debilitating neuropathic pain condition. Current pharmacologic therapy can be inadequate and intolerable for patients. We present a case of a gentleman with refractory postherpetic neuralgia in the intercostobrachial nerve distribution that was successfully treated with cryoneurolysis/cryoanalgesia therapy.

Long-latency reflexes of elbow and shoulder muscles suggest reciprocal excitation of flexors, reciprocal excitation of extensors, and reciprocal inhibition between flexors and extensors.

Postural corrections of the upper limb are required in tasks ranging from handling an umbrella in the changing wind to securing a wriggling baby. One complication in this process is the mechanical interaction between the different segments of the arm where torque applied at one joint induces motion at multiple joints. Previous studies have shown the long-latency reflexes of shoulder muscles (50-100 ms after a limb perturbation) account for these mechanical interactions by integrating information about motion of both the shoulder and elbow.
